A. PAXINOS- SHANK STIFFENER Filed Feb. 1929 wfiwss M W Patented May 30,1933 UNITED STATES PATENT OFFICE ANDREW PAXINOS, OF HAVERI-IILL,MASSACHUSETTS, ASSIGNOR, BY MESNE. ASSIGN- MENTS, T0 MOORE SHANKCOMPANY, OF EVERETT, MASSACHUSETTS, A GQRTORA- TION OF MASSACHUSETTSSHANK STIFFENER Application filed February 2, 1929.

The present invention relates to shank stifieners and more particularlyto shank stil'feners for turn shoes or cemented process shoes.

Taking the turn shoe as an example, after the shoe has been turned, aleather shank piece or insole is inserted and is attached at its forwardend to the outsole. Attached to the under side of the insole is a metalshank stiffener or junior which is curved to conform to the shank. Theoutsole and insole are ordinarily cemented together over practicallytheir entire surface and it is desirable, if not essential, that thecemented union shall be nearly perfect over the whole surfaceotherwisethe outsole and insole tend to pull away from each other. l/Vith a metalstiffener, however, a good cemented bond cannot be assured because ofthe fact that the cement does not readily adhere to metal. It has beenproposed to connect the stiffener mechanically to the outsole by meansof prongs or rivets but these expedients are open to objection not onlybecause of increased cost of manufacture, but also because they impairthe beauty and durability of the shoe.

The object of thepresent invention is to provide a metal shank stiffenerhaving provision for complete bonding thereof to the material of theshoe with cement.

To this end, the present invention consists in the shank stiffenerhereinafter described and particularly defined in the claims.

In the accompanying drawing, Fig. l is a side elevation of the turn shoeshank piece with the improved shank stiffener attached to the under sidethereof; Fig. 2 is a bottom plan view of the insole shown in Fig. 1;Fig. 3 is a side view of the shank stiffener; and Fig. 4c is a sectionalview taken through the shank of a turn shoe.

The illustrated embodiment of the invention comprises a leather insoleor shank piece 6 which is molded in the usual shape.

Attached to the under side of the insole is a metal shank stiffener 8having at opposite ends the prongs 9 which are driven into the insole.The metal shank stiffener itself being incapable of being adhered to aleather insole and the outsole.

and the upper 14. A body of glue or cement 16 is received in the spacebetween the The point at which a good cemented bond is most necessary isbetween the shank stiffener and the outsole at the lowermost point ofthe former, which point is indicated at 18. A good bond is assured bythe present invention because of the fact that the fibrous covering forthe shank stiffener is readily adherent to the glue. A good bond betweenthe shank and the sole over the entire surface is accordingly obtained.

It is to be understood that the adherence effected by the cement isbetween the fibrous covering and the outsole. The covering itself isprevented from relative movement on the shank stifiener even though itmay be only loosely placed thereon because of the fact that the metalpiece is held with some pressure between the insole and the Having thusdescribed the invention, what is claimed is:

l. A shank stiffener for shoes comprising a metal piece having means forsecurely attaching it to the shank piece or insole of the shoe, and acovering consisting of a length of fabric tape wound spirally on themetal piece and capable of forming a bond with cement.

2. In a shoe the combination of a leather shank piece, an unyieldingmetal shank stifi- 5 ener securely fastened thereto, a coveringcomprising a length of fabric tape Wound spirally on the shankstiffener, an outsole, and a layer of cement uniting the outsole andshank piece and adhering to the fabric tape.

In testimony whereof I have signed my name to this specification.

ANDREW PAXINOS.
